I have an '08 F-250 with 82k on it. Plan is to order a Mini Maxx, 5" exhaust, EGR delete and coolant filter setup at the end of the week. Do I really need a CAI? I'm doing the mods for reliability, mileage and ability to calibrate for tire size change. Not planning on hot rodding the truck. Wanting a reliable rig for a long way into the future. I recently ordered filters (fuel, oil and air) from dieselfiltersonline and have two new stock air filter elements still in the box.

Reasons I did it was number one better flow, increased turbo sound because the 6.4 is too quiet, and lastly I got a good deal on it. I run afe with dry filter. But running on the lower tunes you shouldn't have an issue. And another thing is people were saying they seen a mpg gain with a cold air intake. I can't verify it because I did everything at once so don't know what exactly what each item did for me.

I run an aFe stage II with PG7 and I can tell you I did gain a little MPG when I switched. That's compared to an essentially new stock air filter. It picked up about 1-2 MPG depending on highway or city driving.

I was skeptical about that, but my log book tells the story.

It makes a high pitch whistle though. Either you like it or you don't. If you don't, get an S&B.

If you are going to run a tune over the 250hp level you will need the intake. Things will get hot in a hurry if you dont. I run S&B because it is quiet and I got a good deal on it. AFE makes a quality filter system as well.

S&b or afe. I have afe and like it better because 1) everybody on this forum has an s&b. 2) they flow the same basically. 3) I don't have the same cai everybody on this forum has lol.

I get that it's your opinion and choice, but I couldn't bring myself to pay more for the same performance. I do like the look of the AFE better, but I have to pick performance per dollar every time if I can...
